V gum I Patented June 3, 1930 UNITED STATES P A 'TENT OFFICE WILLIAM H. no'sE, or JERSEY c'ITY, NEW JERSEY CONTAINER CLOSURE Application, filed March 13, 1928. Serial No. 261,259.

My invention relates to container closures and refers particularly to devices of this character having locking pronged tongues.

ment of locking prongs whereby the attachment of my 'device to a container will cause incisions Within the side of the container of practically the same size as the prongs inserted therein. I I

I Another object of my invention is a closure in which'the tongues carrying the locking prongs will be maintained in abutment with the container side and protected against accidental displacement.

The above mentioned, and other, advantageous features of my device will be evident upon a consideration of my specification and its accompanying drawings. 7

My device in a generalway comprises a central portion having a downwardly extended annular flange, preferably U-shapedcarrying a plurality of spaced dependent tongues, the

side of each tonguecarrying a plurality of inwardly turned prongs;

. Further, I prefer that each prong should be of such shape that the upper edge thereof will bear right angles to the edge of its tongue,

' and a consideration of the accompanying drawings will indicate the advantages of this particular formation of prong. In operation, my device is placed upon, or over, the open-end of. a container, the 40 flange abuttinguponthe upper outer face of the container side, and the tongues bent with the container side. When the device is thus positioned the tongues are bent inwardly until they abut upon the outer face of the container side, the prongs being thus forced into the said side. A a

It is naturally advantageous that the prongs be retained as firmly as possible with in the container side and this is best accomplished by having the incisions within the side the same size as the prongs therein.

A consideration of this locking movement will indicate that by having the upper edge of a prong at right angles to the edge of its tongue, this movement will move the upper edge of the prong in the arc of the circle of its tongue movement, thus causing the prongto enter the container side at a right angle thereto, thus producing an incision the size of the prong.

A further advantageous featureof prongs upon the sides of the tongues is that it binds the latter to the container side preventing accidental displacement. V v

In some modifications of my device I'employ rods or hands encircling the tongues with means removably locking the band to the tongues to prevent accidental displacement of the device. .7 In the accompanying drawings illustrating modified forms of the device of my invention, similar parts are designated by similar numerals.

Figure lO i's a vertical cross-section of a modified form of my device.

The particular form of the device ofmy invention shown in Figures 1 to 4 inclusive of the accompanying drawings comprises the central annular member '12, having a U- shaped flange formed by the upwardly extongues 16, 16, may also be moved into locked tended element 13, the horizontal element 14 and the downwardly extended element 15. The element 15 is extended into a plurality of spaced tongues 16, 16, the lower portion of each tongue being rolled outwardly and upwardly to form a hook-shaped holder- 17 for the binding ring 18. Each side of each tongue 16 carries a plurality of inwardly extended prongs 19, 19, the upper edge face of each prong being at right angles to the face of the tongue. A projection 20 carried by each tongue 16 prevents the accidental upward movement of the binding ring 18.

The operation of my device is as follows My device is placed upon the annular side .2101? a receptacle as shown in Figure 3, the

tongues 16, 16, are then placed inwardly in the .directionof the arrow of Figure 3, and

the binding ring. 18 then moved downwardly into position in the hooked member 17 The positionby moving the ring 18 downwardly over the extended tongues.

As the upper edges of the prongs 19, 19, are

atright; angles to the face of its tongue, these prongs will enter the receptacle side 21 at practically right angles and hence each in- I ;cision made within the receptacle side will be of the exact size of its. prong, which would notbe the case if the prongs were positioned angularly otherwise, and this fitment of prong and 1I1C1S1OI1 insures a firmer locking engagement than is otherwise possible.

- In themodiflcation shown in Figure 5, the

hooked member 22 is longer than the previ- .ously described hooked member 17, and hence, can be formed slightly around the ring 18 after the latter is in place thus obviating the necessity of the projection 20.

In the modification shown in Figure 6, the bar ring18 is replaced by a band ring 23.

. ,In the modification shown in Figure 7, the

hooked member 17 of Figure 6 is replaced with a shoulder extension 24,

In the modification shown in Figures 8 and 9., each tongue 16 has an end prong 25 in addition to the sideprongs '19, 19,.

In the modification shown in Figure 10,

the, rojection 2Q oteach tongue 16, is beneath the inding band 2 6 which has an annular vgroove 27 into which the projection 20 will e positioned when the band 26 is in locking position. 4

I do not limit myself to the particular size, shape, number or arrangement'of parts as shown and described as these are given simply as a means for clearly describing the deice of my invention.

What Iclaim is r j 1. In a container closure of sheet-material, in combination, a central portion adapted to cover the open portion of a container; a dependent peripheral flange carried by said central portion adapted to abut upon the sides'of a container;a plurality of dependent spaced tongues carried by said flange; a plurality of inwardly extended flat prongs carred by each side of said tongues, the plane of said tongues being angularly positioned to the plane of said central portion and parallel to the longitudinal axis of a container to which said device is attached, and means independent of said prongs preventing the vertical movement of said device when positioned upon a container.

2. In a container closure of sheet material, in combination, a central portion adapted to cover the open portion of a container; a dependent peripheral flange carried by said central portion adapted to abut upon the sides of a container; a plurality of dependent spaced tongues carried by said flange; a plurality of inwardly extended flat prongs carried by each side of said tongues, the plane of said tongues being angularly positioned to the plane of said central portion and parallel to the longitudinal axis of a container to which said device is attached, and a closed ring capable of downward movement over said tongues, such movement forcing the prongs into the side of a receptacle upon which the device is placed.

3. In acontainer closure of sheet material, in combination, a central portion adapted to cover the open portion of a container; at 'de pendent U-shaped peripheral flange carried by said central portion adapted to abut upon the sides of a container; a plurality of dependent spaced tongues carried by said flange; a plurality of inwardly extended flat prongs carried by each side of said tongues, the plane of said tongues being angularly positioned to the'plane of said central portion and parallel to the longitudinal axis of a container to which said device is attached, and means independent of said prongs preventingthe vertical movement of said device when positioned upon a container. 4.
